Infusion: Testia automates the monitoring of manufacturing processes

Generated using linear sensors to detect process deviations at an early stage, In-line Infusion Monitoring’s real-time information can be used to guarantee high-quality parts, reduce process development time and automate controls.

Unlike its competitors, the solution developed by Testia does not use point sensors: it evaluates the progress of the flow using linear sensors that enable spatially resolved data to be interpreted.

The solution is available in 2 versions: a portable device for process development and an embedded system for integration within industrial processes. These different versions meet the needs of different customers, whether in research and development, process industrialisation or mass production.

‘Our sensors are designed to operate in combination with all standard fibre, resin and tooling materials, and to withstand temperatures of up to 200°C. They can therefore be used in a wide range of industries, including aerospace, wind energy, marine, transport and automotive,’ says Christopher Buchmann, product manager for In-line Infusion Monitoring. He also points out that Testia offers ‘linear sensors from as little as 0.1mm, which reduces the effect on the infusion process to a minimum’.

A customisable solution that enables digitalisation in production

The In-line Infusion Monitoring technology package combines the monitoring device with a software framework to enable intuitive interpretation of the recorded data. This configuration provides the operator with real-time information on the position of the flow front, which is easy to interpret and enables the manufacturing process to be adapted according to the data measured.

Testia offers different sensor geometries depending on the application. Specially designed components will be available for different applications, such as vacuum-tight connectors for LRI processes and feedthroughs with increased pressure resistance for RTM processes. The focus is also on tooling for integrated sensors, which are particularly attractive for industrial applications because of their low recurring costs. Cables of various lengths will complete the product range, ensuring a highly versatile application.

‘We see our technology as a catalyst for the digitalisation of production, because the digital interfaces can also be customised,’ adds Christopher Buchmann. ‘This means that the system can be easily integrated into our customers’ production lines.

Among the early adopters, Axel Herrmann, CEO of CTC GmbH, said: ‘In RTM processes, small deviations can have a big impact. Thanks to the In-line Infusion Monitoring technology, we can monitor in real time whether the process is proceeding as planned and optimise the infusion strategy accordingly.’
